Cross sections and production yields of ^117mSn and other radionuclides generated in natural and enriched antimony with protons up to 145 MeV

Abstract

Abstract Cross sections of a prospective medical radionuclide 117m Sn along with 113 Sn, 120m,122 Sb, 111,114m In and 118,119m,119g,121m,121g,123m Te generated in natural and enriched antimony targets by protons in a wide energy range up to 145 MeV were determined. A stacked-foil technique followed by gas chemical separation and γ-ray spectrometry were used. The obtained data were compared with experimental values reported in literature and with theoretical computations by ALICE, TALYS and Cascade-Evaporation-Fission codes. Production yields of 117m Sn and the main impurity 113 Sn were estimated for different irradiation modes.
